- You may be looking for the Dark Time.
The Dark Times was one of the earliest aeons in the history of the universe.
Occurring after Gallifrey was born, (COMIC: Agent Provocateur) the Tenth Doctor described this as a time of chaos "before our reality" when the Nestenes and Great Vampires flourished, (TV: The Infinite Quest) as well as the Carrionites. (TV: The Shakespeare Code)
The Mandragora Helix also originated during this era. (PROSE: Beautiful Chaos) The Great Old Ones were also present in the universe at this time. It was during this time period, too, that the legendary spaceship Infinite was created. (TV: The Infinite Quest)
